The correct choice is (b) Nickle

To explain: Nickle is used in many organisms for their growth purposes as they are used as a component of hydrogenase in various microorganisms, Nickle can stimulate chemolithotrophic growth in bacteria. But Uranium is radioactive and highly toxic, copper and cadmium are toxic and they do not stimulate chemolithotrophic growth in bacteria.
